JACOB ZAG-EL, OF CHICAGO, ILLINOIS, ASSIGNOR 0F ONE-HALF TO JOHN A. SODERSIROM, OF CHICAGO, ILLINOIS.

NEGKTIE-FASTENER.

Specification of Letters Patent. Patented 111108 17, 1919.

Application filed October 8, 1918. Serial No. 257,393.

To all whom it may concern:

Be it known that 1, Laws ZAGEL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Necktie-Fasteners, of which the following is a specification.

The invention relates to improvements in fasteners for bow ties and more particularly is an improvement upon the type of fasten ers which secure the tie aflixed thereto to the collar of the wearer by engaging portions of the collar between two metallic members of the fastener normally held together by 1e)lastic pressure exerted between the memers.

It has heretofore been proposed to construct metallic tie fasteners of two pieces of metal, one or both of which are elastic and to secure the same together by riveting or by the use of some separate securing means as a metallic staple. A more approved construction consists in forming a relatively rigid metallic element with integral branches or tongues on opposite sides near its central portion which branches or tongues are adapted to be bent over and around a metallic spring element so as to clamp the two parts firmly together, leaving their cooperating extremities engaging each other under the pressure of the spring element. In such constructions great difficulty has been experienced in the manufacture of the element having the securing branches or tongues, because of the tendency of the metal adjacent the base of the branches or tongues to crack or separate in use and eventually resulting in the weakening and breaking of this part of the fastener. It is therefore the object of the invention to construct the relatively rigid element of the necktie fastener having the securing branches or tongues in such a manner that these parts will be practically indestructible and completely eliminating the tendency to cracking or breaking of the same by reason of the strains placed thereon incident to use.

In the accompanying drawingsforming a part of the specification, Figure 1 is a view of a bow tie showin the fastening device embodying the invention secured to the back thereof, and Fig. 2 is a top plan view of the same with part of the tie broken away to disclose the invention. Fig. 3 is a perspective view of the rigid element of the metallic fastening device showing.

the construction embodying the invention and Fig. 4 is a side elevation of the same element showing the same resting on one longitudinal edge, which is the normal position of the part in use. Fig. 5 is a perspective view of the elastic or spring element of the fastening device, and Fig. 6 is a top plan view of the two elements secured together showing the fastener composed of the two elements secured together lying on its longitudinal edge, which is the normal position of the same in use.

The reference character 10 is applied to the material of the bow tie, Figs. 1 and 2. The spring element 12, Fig. 5 is preferably constructed of a flat piece of spring stee-l,the main body portion being given a curve of relatively long radius and being preferably reversely curved near its extremities. Cooperating with the spring element 12 is the relatively rigid element designated generally by the reference character 13, Figs. 3, 4 and 6, having an abrupt crimp or transverse groove 13" midway between its longitudinal extremities. Intersecting the crimp or transverse groove 13 in the element 13 is a longitudinal ribl3 formed of the material of the body of the element 13 by pressing the same from the convex to the concave side of the element thus forming a groove on one side of the element and a rib on the other side and tending to increase many fold the strength of the element against flexing or bending near its middle part adjacent the transverse groove 13 On each side of the groove 13 at the lateral edges of the element 13 there are formed integral tongues designated by the reference character 13. These tongues 13 are formed in the operation of stamping or cutting the I element 13 from a blank or sheet of mate rial, and it has heretofore been the practice to construct the element 13 of uniform width throughout to the base of the integral tongues 13", the latter extending abruptly from the longitudinal edges of the material. Losses due to defective parts owing to the tendency of the material to start to crack at the base of the tongues 13, which subsequently increases to a break causing failure of the part, have been very considerable and in some cases such failure of the part is due to cracks which have a tendency to start at the base of the tongues 13 after the parts are put to use.

I have discovered that by making the element 13 so that the side edges of the tongues.

13 will be extended or out downwardly into the material of the element 18 011 a gradual curve which extends thence outwardly, forming-the curved notches 13 on each side of the tongues as indicated in Figs. 3, 4E and 6 and avoiding all sharp angles at thev base of the tongues 13? I am able to eliminate practically all losses due to defects, at this point in the element 13. It will be obvious that in. the cuttingaway of the material at the notches 13 the strength of the element 13 near its central portion may be somewhat impaired, but I find that by using care in forming the longitudinal rib 13 so that it completely intersects the central transverse groove 13 the element may be made so strong that no flexing or bending in) ordinary use. need occur at any portion of the element through which the longitudinal strengthening rib extends and if any flexing or bending of the element takes placeit willv be beyond the extremities of the strengthening rib 18 adjacent the extremities of the element.

The spring element 12v has formed on its opposite side edges intermediate its. extremities the notches 1.2 with which the tongues 13' are adapted to cooperate when the parts are fastened; together as shown in Fig.- 6. The spring element 12 may be provided with other notches as indicated at 12 and 12 for the attachment of the. covering cloth or shield as indicated at 1-5. and forshielding securing threads by which the fastener may be attached to the material of the bow tie. In using the fastening device, it be ing secured to the back of the bow tie as illustrated in Figs. 1 and 2, its attachment to the collar of the wearer will be apparent, it being understood that the fastener is primarily adapted for usewith. collars of the turndown variety and the free ends, of the Copies of this patent may be obtained for! five cents each, by add-ressing the spring element 12 will be pressed outwardly and apart from the relatively rigid element 13, and the tie may then be inserted in position at the front opening of the collar with the folds of the turndown collar betweentween theelements 12 and 13 of the fastening device.

I claim:

'1. A necktie; fastener comprising ametallic spring element, and a second element formed of. an, elongated fiat piece of metal having tongues formed integrally with the material thereof on opposite sides intermediate its ends, the sides of: said tongues adjacent the bases thereof being extended outwardly and into the material of the body of the metallic element whereby cut-away portions or notches are formed adjacent the bases of each ofthe said tongues and extending intothe material of the body portion of the element. r

2. A necktie fastener comprising a metallic spring element, a second element formed. of an elongated fiat piece of. metal having a transverse groove therein inter.- mediate, its extremities and. a strengthening rib formed out of the material of thebody of said second element and intersecting. the transverse groove therein, and tongues formed integrally with the material of said second element on opposite sides of the said groove intermediate the extremities of the element, the sides of said tongues adjacent the basesv thereof being extended outwardly and into the material of the body of the metallic element whereby cut-away portions or notches are formed adjacent the bases of each of said tongues and extending into the material of the body of the element.

In testimony whereof Ihave signed my name to this specification onthis 21st day of September, A. D. 1918'.
